OBJECTIVE To discuss the therapeutic effect of one stage surgical treatment in the multiple primary hypopharyngeal and cervical thoracic esophageal carcinoma.METHODS The thoracoscopy group: dissecting the esophagus and mediastinal lymph node assisted with thoracoscope, and then opened abdominal cavity to make gastric tube. Head and neck group: doing the cervical lymph node dissection, total laryngectomy, total hypopharyngectomy and total esophagectomy, and then anastomosis of the pharynx with gastric tube. All cases were received conventional radiotherapy and chemotherapy after operation.RESULTS All the cases in this group were successfully underwent the one stage operation. The postoperative complications were pulmonary infection in 3 cases, pleural effusion in 2 cases and tracheal tear in one case. No anastomotic fistula or postoperative deaths occurred. The 3 and 5 year survival rates were 63.6% and 50.0% respectively.CONCLUSION It should take necessary examinations of cervical thoracic esophagus to prevent missing the multiple primary carcinoma of the hypopharyngeal carcinoma. The total laryngectomy, total hypopharyngectomy and total esophagectomy, and anastomosis of the pharynx with gastric tube for multiple primary hypopharyngeal and cervical thoracic esophageal carcinoma is a feasible and active treatment method.

Objective To observe whether hepatitis B vaccine enhance the treating effect of cyto-kine induced kill(CIK) cells on hepatitis B virus transgenic(HBV-Tg) mice. Methods The HBV-Tg mice were treated with CIK cells by peritoneal injection and hepatitis B vaccine by hypodermic injection. The HBV DNA level were tested by real-time PCR,T lymphocyte subgroup were detected by flow cytometry and the pathological diversify of hepatic tissue were observed by HE staining. Results The HBV DNA loading in peripheral blood of HBV-Tg mice decreased after CIK cells were treated and CD3~+ , CD4~+ and CD8~+ cells increased which were enhanced after CIK cells combined with hepatitis B vaccine. Conclusion Hepa-titis B vaccine enhanced the treating effect of CIK on HBV-Tg mice which may be implemented by increased the blood level of CD3~+, CD4~+ and CD8~+ cells, especially CD8~+ cells level.

Objective To explore the effect of Yunnan specialty rice products on blood sugar by measuring the glycemic index of 5 Yunnan special rice foods:rice noodles,rice cakes,rice rolls,sour rice noodles and dry rice noodles.Methods Following the national standard method to determine the carbohydrate content of 5 Yunnan specialty rice products,and the target amount of the test substance was calculated.Food Glycemic Index Determination Method was used to determine the glycemic index of 5 Yunnan specialty rice products and observe their impact on blood sugar.Results The GI value of Yunnan specialty food rice noodle is 63,rice cake is 64,rice roll is 46,sour rice noodles is 38,and dry rice noodles is 33.Conclusion Yunnan specialty foods rice noodle and rice cake belong to medium GI foods,and diabetes patients should reduce consumption;rice roll,sour rice noodles,and dry rice noodles belong to low GI foods and can be a better staple food source for diabetes patients.

Objective:To investigate the effect of prolonged negative pressure drainage time after parotidectomy and analyze its relationship with the incidence of postoperative salivary fistula.Methods:The clinical data of 94 patients with benign parotid gland tumors who received treatment in the Department of Otolaryngology-Head and Neck Surgery of The First Affiliated Hospital of Xiamen University from July 2021 to June 2022 were retrospectively analyzed. These patients were divided into an observation group and a control group ( n = 47 per group). In the observation group, the negative pressure drainage tube was removed after 1 week of simple negative pressure drainage, while in the control group, conventional local bandaging of the parotid gland was performed for 2 weeks, and negative pressure drainage was given for 2-3 days. Postoperative drainage volume, pain degree, and the incidence of salivary fistula were recorded for each group. Results:The total drainage volume in the observation group was (77.93 ± 23.83) mL, which was significantly greater than (47.06 ± 24.71) mL in the control group ( t = 6.17, P < 0.001). The Visual Analogue Scale score in the observation group was (3.021 ± 1.07) points, which was significantly lower than (7.53 ± 1.27) points in the control group ( t = 18.63, P < 0.001). The incidence of postoperative salivary fistula in the observation group was 2.1% (1/47), which was significantly lower than 17.0% (8/47) in the control group ( χ2 = 4.42, P = 0.035). Conclusion:Simple prolongation of negative pressure drainage time can achieve full drainage, improve the quality of life of patients after parotidectomy and reduce the occurrence of postoperative salivary fistula, which is worthy of clinical promotion.

Objective　To observe the incidence of white matter hyperintensities （WMHs） and the distribution of right to left shunt （RLS） in migraine patients，and to explore whether WMHs is related to RLS. Methods　106 patients with migraine were selected as the research objects. The basic data and clinical information of migraine were collected. The WMHs were evaluated by cranial MRI. The RLS was diagnosed and graded by transcranial Doppler （TCD） bubbles test. The correlation between WMHs and RLS was analyzed. Results　Among 106 migraine patients，33 （31.1%） were in WMHs+ group and 73 （68.9%） in WMHs- group. The total positive rate of RLS was 48.1% （51/106）. The distribution of different shunt levels was as follows：grade Ⅰ shunt in 27 cases （25.5%），grade Ⅱ shunt in 4 cases （3.8%），grade Ⅲ shunt in 6 cases （5.6%），grade Ⅳ shunt in 14 cases （13.2%）. In "WMHs+" group，there were 5 cases of grade Ⅰ shunt，1 case of grade Ⅱ shunt，3 cases of grade Ⅲ shunt and 10 cases of grade Ⅳ shunt；in "WMHs-" group，there were 22 cases of grade Ⅰ shunt，3 cases of grade Ⅱ shunt，3 cases of grade Ⅲ shunt and 4 cases of grade Ⅳ shunt. Compared with "WMHs+" group and "WMHs-" group，there was no statistical difference in the overall positive rate of bubbles test between the two groups （P>0.05，χ2=1.719），but the large shunt rate of "WMHs+" group was significantly higher than that of "WMHs-" group （P<0.01，χ2=13.188）. Conclusion　There is no significant correlation between WMHs and RLS in migraine patients，but large RLSs will increase the risk of WMHs in migraine patients.

Objective:To report our experience of treating open comminuted limb fractures caused by gunshots using the Masquelet technique.Methods:Between January 2016 and July 2018, 3 patients were admitted to Institute of Orthopedics, 920 Hospital of Joint Logistic Service of People's Liberation Army for open comminuted limb fractures caused by gunshots.They were all male, aged from 18 to 41 years (average, 30.7 years).Their fractures were complicated with perforating wounds and belonged to Gustilo type ⅢB for open fractures.The bone defects were 5 to 9 cm in length (average, 6.7 cm), located at the proximal femur in 2 cases and at the upper middle humerus in one.They were treated by standard Masquelet technique at 2 stages.The postoperative functions of the hip, knee and shoulder were evaluated according to the Harris hip score, Lowa knee score and Constant-Murley shoulder function score.Results:The 3 patients obtained an average follow-up of 17.3 months.The bone defects were all repaired in the 3 patients without any signs of infection.The 2 patients with femoral defects were rated as both excellent by the Harris hip score, as excellent in one and as good in the other by the Lowa knee score; the patient with humeral defects was rated as excellent by the Constant-Murley shoulder function score.Conclusion:Masquelet technique is a desirable treat-ment of segmental long bone defects caused by gunshots.
